Nowadays don't make page deal with anyone.... Facebook introduced a new trick through which you can put an hidden admin and if some one remove you on your page you can recover your page again So create a new g.mail or yahoo account and add it as a page manger. If you make any deal and someone hack you can also get your page again. You can deal with the people whom you know and whom you think they'll not cheat you. I also don't know that trick of recovering page. I also don't know the trick of hidden admin.
